Subject: [HACKERS] linux/alpha patches

These patches lay the groundwork for a Linux/Alpha port.  The port doesn't
actually work unless you tweak the linker to put all the pointers in the
first 32 bits of the address space, but it's at least a start.  It
implements the test-and-set instruction in Alpha assembly, and also fixes
a lot of pointer-to-integer conversions, which is probably good anyway.
